Add a little more liquid so that the meniscus will be exactly at the same level of the ring mark.
Pay attention to read the meniscus at the eye level also not to wet the inner neck wall above the ring mark.

Bulb maufactured from natural rubber. Most common pipette filler for all types of pipettes up to 100 ml volume. Standard model can be used up to 10 ml pipettes. Universal model can be used up to 100 ml pipettes.
Evacuation can be easily done by pressing the related automatic valves. Offers an easy single hand use. Pressing the valve the liquid is drawn- up to the desired level, dispensed partially or blown-out.
Simple and easily controllable pipette filler for all pipettes up to 15 ml volume .
Very easy to use; First squeeze the bulb and release the air inside. Then attach the pipette. Release the bulb pressure and fill the pipette. For discharge squeeze the bulb again.
Manufactured from silicone. Ideal for simple pipetting applications.
Offered with three different volume capacity.
Standard pipette filler for up to 10 ml pipettes.
Universal pipette filler for up to 100 ml pipettes.
Volume lock feature allows selecting the desired volume and locking the indicator to achieve a more reliable pipetting experience.
Locking feature prevents accidental volume changes during pipetting procedures.
Simply slide the button to the upper position to lock or lower to release.
Dual “O” ring technology: guarantees best tip fit.
Outer “O” rings make tip loading easier. The first “O” ring creates a smooth seal while the second “O” ring creates a posi-tive stop to ensure that the tips are airtight, sealed, and can be ejected with the small-est amount of force.
tips are made from low liquid retention resins that
provides superior sample recovery while increasing accuracy and
reproducibility.
Allows for complete retrieval of precious samples.
Saves costly reagents by reducing sample loss.
Optimizes accuracy of the pipettor and also transfer of blood plasma.
Avoids denaturation of nucleic acids and protein samples.
filter tips offer the ultimate in protection against
contamination.
Filter barriers block aerosols by coalescing radioactive, chemical or biological contaminants before they can come in contact of pipettor shaft.
Their usage is mostly essential in critical applications such as PCR, DNA sequencing and other techniques that involve the use of vaporous, biohazardous or corrosive material.
Tip filters also act as a safety barrier against accidental over-pipetting of liquids without risk of sample lock-up.
